Installing Docker

Alpine Linux

Docker is a powerful tool for running and managing containerized applications. It allows developers to package their applications and dependencies into lightweight containers that can be easily shipped and run on any platform. In this tutorial, we will show you how to install Docker on Alpine Linux, a lightweight distribution based on the musl libc library and busybox utilities.

Prerequisites

Before starting, you will need to have a server running Alpine Linux. You can install Alpine Linux on a physical machine or on a virtual machine using tools like VirtualBox or VMware.

Installing Docker

Installing Docker on Alpine Linux is straightforward. First, update the package manager’s package index by running the following command:

apk update

Next, install Docker by running the following command:

apk add docker

This will install the Docker engine, as well as the docker and docker-compose command-line tools.

Starting Docker

After installation, start the Docker daemon by running the following command:

/etc/init.d/docker start

You can also start Docker automatically on boot by running the following command:

rc-update add docker default

Testing Docker

To test your Docker installation, run the following command:

docker run hello-world

This will pull and run the hello-world image, which displays a message confirming that Docker is working correctly.

Conclusion

In this tutorial, we showed you how to install Docker on Alpine Linux. You can now use Docker to run and manage containerized applications on your Alpine Linux server. To learn more about Docker and containerization, check out the official Docker documentation.
